Detailed Description

QGLColormap provides a platform independent way of specifying and installing indexed colormaps for a QGLWidget. QGLColormap is especially useful when using the OpenGL color-index mode.

Under X11 you must use an X server that supports either a PseudoColor or DirectColor visual class. If your X server currently only provides a GrayScale, TrueColor, StaticColor or StaticGray visual, you will not be able to allocate colorcells for writing. If this is the case, try setting your X server to 8 bit mode. It should then provide you with at least a PseudoColor visual. Note that you may experience colormap flashing if your X server is running in 8 bit mode.

The size() of the colormap is always set to 256 colors. Note that under Windows you can also install colormaps in child widgets.

Set an array of cells in this colormap. count is the number of colors that should be set, colors is the array of colors, and base is the starting index. The first element in colors is set at base in the colormap.
